Product Description
PS914 Von Duprin Power Supply — 4A High Inrush
Expert's Note: The PS914 is what you spec when your electrified exit devices draw heavy on initial activation. That 16 amp inrush rating handles the spike when EL trim energizes — standard 4 amp supplies can brown out on that first hit and cause nuisance lockouts. If you're getting intermittent failures on activation, an undersized supply is usually the culprit. The PS914 solves that.
Field selectable 12/24 VDC output with universal 120-240 VAC input — works on any commercial building power without a transformer. UL294 listed, Class 2 rated. The 14x12x4 enclosure accepts up to two optional distribution boards plus battery backup. Regulated and filtered DC outputs keep your electronics clean.
